Maybe that could protect the colonists moving west.
After Britain won the Seven Years' War, the natives became furious because they lost land. The Native Americans attacked colonists. King George tried to stop it by making the proclamation line.
We should make an imaginary line running down the crest of the Appalachian Mountains.
Yes sir!
Go and make sure no one moves west of the Appalachian Mountains.
The colonists became furious because they fought for land but now they have nothing.
I can't believe we have to listen to these dumb rules!
We fought for land but now we get nothing.
We are not going to listen to these rules anymore!
They ignored the Proclamation
That's how the rules work!
The settlers ignoring the proclamation led to the American revolution because it was the start of them rebelling against the British.
